Answer:
29.3 feet
Step-by-step explanation:
Okay I don't know the equation to put it in, but all you need to do is add the two values together.
12.4 + 16.9 = 29.3 feet
86 divides by 9 sequels to 9 Remainder 5 and 95 divided by 10 equals to 9 Remainder 5
3+16=19,
3+20=23
So the correct answer would be 19 and 23
